CANOPY-HOLDER FOR CHILDRENS CARRIAGES.

SPECIFICATION forming part of Letters Patent No. 461,373, dated October13,

Application filed July 27,1891. Serial No. 400,805. (No model.)

To @ZZ whom 7525 may concern,.-

Be it known that LADoLPHUs G. SNELL, a citizen of the United States,residing at New Haven, in the countyof New Haven and State ofConnecticut, have invented a new and usen joint of two members looselyconnected or linked together, the whole being manufactured andconstructed in the manner hereinafter more fully described, and theappearance of the finished article being substantially that shown on thesheet of drawings, wherein Figure l is a side'elevation of a top-proprod or support, an umbrella canopy, and my irnproved joint between thesemembers. Fig. 2

isan enlarged front elevation of my improved joint with the yoke partlyin section. Fig. 3 is a side elevation thereof with the ring Yandtop-prop rod in section. Fig.- 4 is a detail of .a slight modification.

Referring to the said drawings, the letter P designates a rod adjustably secured in and rising from a socket at the back of thecarriage-body and extending thence forwardly over -said body. T is thetop, which in the present case is an umbrella vor parasol, and .I is myimproved joint, connecting the parasol to the rod in such manner thatthe former can be set at. any desired point on and at any angle to thelatter, all as is well known in devices of this character.

The present invention contemplates the provision of anewjoint J, capableof the same functions as those heretofore used, as shown, but whoseconstruction and whose process of manufacture differ to an extent fromthose of similar devices now on the market, the result being that abetter article is produced at less cost, in shorter time, and by thesaving of considerable labor. The j oint'which I thus referto comprisesa bell B, preferably having a knob K at its upper end, through Varyaccording as the which extends an integral ring R. In the lower end ofthis bell is secured in any suitable manner-for instance, by a set-screwS', as shown.V

Y is a yoke, having an opening O transversely through i's body, closedatits lower end E, this opening loosely embracing the ring R and the rodP, and the entire yoke being of a single piece of casting.y

S is the usual set-screw, which passes downwardly through the yoke, andwhose ti p bears the. rod with considerable force against the ring, andby this screw the angles of the yoke the staff of the top T on the rodand the ring inthe yoke can be adj usted.

In the inanufactureof this improved joint the bell, knob, and ring arefirst cast in a single piece. This casting is then laid in a flaskprovided with a inold for the yoke, the ring intersecting the mold atthe point Where the opening C in the yoke-is to occur, and the ring atthis point being surrounded by a sand core in the well-known manner 'ofproducing castings one of which is linked into or passed loosely throughan opening in the other. The metal is then poured and the yoke isformed. From three hundred to four hundred pounds of the connectedcastings are then put into a barrel, which is afterward filled withwater and sealed, and the whole is rotary,oscillatory, or vibratorymotion, known as tumbling, which is continued for perhaps a week, andwhen the castings are taken from the barrel' they will be found to besmooth and nicely rounded, perhaps as well finished as though all partsof each had been ground on an emery-wheel. The castings are then tin nedwith what is knownfto the trade as X. C. plate, or they may be nickeledor. japanned, as preferred. Before or after such finishing the yoke isbored longitudinally and threaded to receive the screw S, which is alsofinished in a manner to correspond with the balance, of the casting, asis the screw S if it be used. The complete jointis then ready to put onthe -market,'and the size of the part-s or the dimension of the openingmay, of course,

taste of the manufacturer may dictate or the diameter of the rod P maynecessitate;- but these variations will be well understood by thoseinterested in or familiar withthe art.

subjected to a ICO ywind. or by Instead of casting the yoke around thering in the manner above described,l mayin some cases cast it or produceit in malleable iron in the form shown in Fig. i and then connect itwith the ring by bending its arms together while hot and riveting,brazing, or otherwise connecting the lower ends of said arms within thering, and practice and experience may teach that this is a lessexpensive manner to form the connected members than the above process.Izlowever, the resulting article possesses practically all theadvantages of the one described above, and I suggest this modiied modeof its manufacture to show that I am not limited to the single processabove set forth.

Referring to Fig. 2 it will be seen that the lower side ofthe openingthrough the yoke is cast on a curve C of greater radius than that of theinside of the ring R, and by reference to Fig. 8 it will be observedthat the transverse curvature of the bottom of this opening isapproximately the same as that of the ring in section. Vith thisconstruction (which, it will be obvious, can be given the parts evenwhen they are cast) the inside of the ring bears at only two pointsagainst the opening O through the yokenamely, at each end of theopening, as illustrated in Fig. l-while the sides of the ring bearagainst the sides of the opening at all points across the yoke, and therod is pressed by the screw at only one point against the outer side ofthe ring. Thus it will seen that the ring is supported at two points asagainst a downward pressure at one point, which is always between thosetwo, while all lateral motion of the ring within the yoke, and hence allliability of the parts to slip and allow the connection to become looseisf avoided by the sides of the ring at all times striking the sides ofthe yoke. This construction permits t-he screw to be set much tighterthan if the yoke were open at its side, as is the case in a joint ofthis character which is now on the market. It gives three bearing-pointson the ring, and it has no angles to mar the ring and presents nopossibility of the latter slipping beneath the rod, even when the top issubjected to considerable strain, as in the the rough handling of theoperator or of an infant.

What is claimed as new isl. The herein-described joint,thesamecomprising a bell having an integral ring, a yoke having alateral opening integrally closed on all sides and through which saidring passes, and a screw passing downwardly through said yokeand intoits opening,l as and for the purpose set forth.

2. The herein-described joint, the same comprising a bell, a knob, and aring, all of a single casting, a set-screw through the side of the bell,a yoke having a lateral opening closed on all sides and through whichsaid ring passes, this opening being also adapted for the reception ofthe prop-rod, and a screw passing through the yoke, with its pointadapted to bear against said rod, as and for the purpose set forth.

3. In a joint of the character describechthe combination, with the belland ring, of the yoke having a lateral opening closed on all sides andthe longitudinal curvature of whose bottom is less than thecorresponding curvature of the inner side of said ring which passesthrough said opening, and a screw passing downwardly through the yokeinto its opening, as and for the purpose set forth.

4. In a joint of the character described, the combination, with the belland ring, of the yoke having a lateral opening closed on all sides andthrough which said ring extends, the width of the opening at its lowerend being substantially the same as the thickness of the ring, thuspermitting the slipping but preventing the turning over of the ring,-anda' screw passing downwardly through the yoke into its opening, as andfor the purpose set forth.

5. In a joint of the character described, the combination, with the belland ring, of the Yoke having a lateral opening closed on all sides andthrough which said ring extends, the curvature of the bottom of saidopening bein glongitudinally less than the corresponding curvature ofthe inner side of the ring and the width of said opening transverselythe same as that of the ring, and a screw passing downwardly through theyoke into its opening, as and for the purpose hereinbefore set forth.

In testimony that I claim the foregoing as my own I have hereto aflixedmy signature in presence of two witnesses.
